The Multiquip 3216 Cotter Pin is a genuine OEM fastening component designed for a wide range of Whiteman walk-behind and ride-on power trowels, Multiquip masonry saws, and wheel kit accessories. As a direct OEM replacement, the 3216 meets the exact material and dimensional specifications set by Multiquip, ensuring a correct fit across every compatible application. Confirmed fitment includes trowel models CA4HM, CA4HC, CA5BC, and the JTO-Series ride-on trowels, masonry saw models MP2090HP, MP2050E3, MP2050E1, MP2H, MP275E3, MP25E3, and MP25E1, and wheel kits UWK1, UWK1A, UWK2, and UWK2A. When it's time for a scheduled service or a field repair, sourcing the correct OEM cotter pin by part number 3216 keeps the job moving without guesswork.
Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's specified metal composition and shear tolerance, ensuring the pin holds under operational load without premature failure or deformation.
- Drop-In Replacement — Matches the original pin diameter and leg length for direct installation into existing clevis, shaft, and linkage mounting points — no trimming or bending required.
- Broad Fitment Coverage — Compatible across Whiteman walk-behind trowels (CA4HM, CA4HC, CA5BC), JTO-Series ride-on trowels, MP-Series masonry saws, and UWK wheel kit assemblies.
- Secure Retention Under Vibration — Cotter pins in trowel and saw applications are exposed to continuous vibration; a correctly sized OEM pin maintains positive retention of shafts and linkage pins throughout the work cycle.
- Safety-Critical Fastener — Cotter pins are locking fasteners that prevent shaft pins and clevis bolts from walking out during operation; using a correctly spec'd pin is essential to safe machine function.
A cotter pin is a split-leg fastening device inserted through a drilled hole in a shaft or bolt to prevent a mating pin, axle, or clevis from backing out during operation. Once installed and bent open, the legs lock the retained component in place, providing positive mechanical retention without threads. In high-vibration equipment like power trowels and masonry saws, cotter pins are a critical last line of defense — a missing or undersized pin can allow linkage components to disengage mid-operation, leading to loss of control or accelerated wear on surrounding hardware.
